Water flows downward along a pipe that is inclined at 40 degrees below the horizontal, as shown. A manometer is used to measure the pressure difference due to gravity and partly due to friction. Determine the pressure difference pa−pb if the length L is 5ft and the height difference in the manometer, h, is 6in. The density of the water is ρ=1.94slug/ft3 and the specific gravity of the mercury is 13.55 . The acceleration of gravity is 32.2ft/s2 and your answer for the pressure difference should be in psi.
